RE: [EnergyPlus_Support] Re: Add/Change Natural ventilation model

Here are lines used to calculate the ventilation flow rate for the ZoneVentilation:WindandStackOpenArea object, extracted from HVACManager.f90.


       Qw = Cw*Ventilation(J)%OpenArea*GetCurrentScheduleValue(Ventilation(J)%OpenAreaSchedPtr)*WindExt

       Qst = Cd*Ventilation(J)%OpenArea*GetCurrentScheduleValue(Ventilation(J)%OpenAreaSchedPtr)* &


       VVF  = SQRT(Qw*Qw + Qst*Qst)


Hope this helps.
